Obviously it is not Gay as it is an inanimate object. It is no different than jerking off with your own hand.

It is anal penetration.... and since it is with one self anal masturbation.

Homosexuality is attraction to the same sex. It has nothing to do with hedonism which is more than likely what this is gyrating toward.

yea, but its not just using a "dildo" in your own butt, you are using a realistic looking penis (replica of yours actually) to do the anal penetration which means there is curiosity there of what it might be like to have a real penis in your butt.
